The Crucial MX100 (128GB-512GB, about $.40 per GB) is one of the cheapest drives on the market because it isn't very good. Crucial has a poor reputation due to buggy drives, mediocre reliability, and not honoring their warranty, but this drive is rather mature so they might finally have it figured out. Not a good choice for OSX due to poor performance consistency. This is a low-endurance drive with a 3 year warranty, or 72 TB of writes, whichever comes first.

You should've bought a Samsung Evo series drive intead.
